Conversion Formula

cm/s² = kn/s × 51.44444444

About Knots per second

The knot per second (kn/s) equals 1852/3600 m/s² ≈ 0.5144 m/s², used in aviation and maritime operations where speed is measured in knots. Aircraft carrier catapult launches accelerate an F/A-18 from 0 to ~150 kn in 2-2.5 s, giving 60-75 kn/s ≈ 31-39 m/s². A commercial jet rejected takeoff from V1 (~145 kn) to rest in ≈25 s decelerates at 5-6 kn/s ≈ 2.6-3.1 m/s². 1 kn/s = 463/900 m/s² ≈ 5.25 × 10⁻² g₀.

About Centimetres per second squared

The centimetre per second squared (cm/s²) is the CGS coherent unit of acceleration, numerically identical to the Gal (1 cm/s² = 1 Gal = 0.01 m/s²). In the CGS system, Newton's second law reads F [dyn] = m [g] × a [cm/s²]. Strong-motion seismology records earthquake accelerograms in cm/s²: the 1940 El Centro earthquake reached a peak ground acceleration of 341 cm/s² ≈ 0.35 g₀. Japan's JMA shindo 7 (structural collapse) threshold is above 400 cm/s². 1 cm/s² = 0.01 m/s² = 1 Gal ≈ 1.02 × 10⁻³ g₀.
